Folomov EDC C1 Flashlight Review

Preface

A new 10440 light has hit the market!  It’s on pre-order at Illumn.com, and the guys there sent an early release model to me for a look.  Of course I’m interested – it ticks a bunch of my boxes.  Nichia, Brass….   Here’s my review of the Folomov EDC C1!


Official Specs and Features

Here’s a link to the product page at Illumn.   The light isn’t up on the official Folomov site yet.

Versions

There is only one version of the EDC C1.

Price

The price is $34.90, and this is available on preorder from Illumn.com.


Short Review

Even though the Folomov EDC C1 doesn’t hit the claimed numbers, I like it a lot.  It’s a complete package light (including the cell) and it is sufficiently bright for the tasks I’ll use it for.  I don’t think the low mode is quite low enough, and the stepdowns on Turbo and High happen too quickly.  But overall I am still very happy with the light.

Long Review

What’s Included

  • Folomov EDC C1 Brass flashlight
  • Unbranded 10440 with charge circuit
  • Spare o-rings (2)
  • Manual

Package and Manual

The EDC C1 ships in a tin, approximately the size of an Altoids tin.  Inside the light is held in place by some foam.

The manual is quite nice, and includes all the specs and other information about the light.  It’s a quite good manual.

Build Quality and Disassembly

There are a couple of things you’ll notice right away when handling this light.  First, is that it is indeed brass.  Second, it’s actually some sort of coated brass.  So there’s a brass smell, and the brass weight, but the light is unlikely to patina very quickly (if at all).

Then you’ll notice that the EDC C1 is a e-switch tailswitch light!  Unusual!

Build quality is good.

Only the tail of the light has a spring.  The head end has only a brass button.

The threads are very short, and square cut (a huge surprise in a light like this!).  The body is highly decorated, which might be seen as good or bad.

The single spring provides adequate protection for the cell, though.

Only the tailcap is removable.  The cell goes into the light in the normal orientation (positive toward emitter).

Size and Comps

Officially: Body Diameter: 13.5mm
Length: 66.8mm
Weight: 34.5g with battery

This is a very small light!  As a 10440 light should be….

It’s not the smallest AAA sized light – in my collection that award goes to the Olight i3E EOS.  Of course that light is a single mode, and the Folomov is quite a bit more feature rich!

Here’s the light in hand.

Retention and Carry

A pocket clip is included and ships attached to the light.  One of the polarizing features of this light is that the clip attaches only on the head, which means bezel-up carry.

It’s a friction clip, and can be removed.  The clip itself is quite nice.  It has a big mouth and ample shoulder, so it’s easy to get on pockets, and roomy enough to sit easily.  I would probably prefer bezel down carry (my favorite AAA light does use that setup) but bezel up isn’t a deal breaker, nor something I can’t get used to.

Power and Runtime

A single 10440 cell powers this light.  Only li-ion will work; other types of AAA sized cells will not.  NiMH, primary alkaline, etc.  Those won’t work.

I performed runtimes with the included cell.  The light never reaches the claimed output of 335 lumens by my testing (corroborated by other more sophisticated testing measures, too).  The initial output on turbo is around 240 lumens by my testing – still quite a respectable number.  I test this to be drawing around 1.5A, too, so there’s not actually too much improvement to be made – this emitter tops out on output at around 2A.

Surprisingly the light doesn’t get all that hot during these tests.

Interestingly the 30 second output is the same for Turbo and High – at a measured 100 lumens.

I tested (but didn’t graph) the light with an Efest 10440, and the output max is the same.  No difference at all.  So while the Folomov 10440 might be smaller because of the charge circuit, it’s just as capable as the Efest 10440’s I have.

See below the charge circuit on the top of this cell.  It’s a micro-USB port – just insert the plug and charging will commence.  While the cell is charging, a red indicator will light on the positive end of the cell.  When charging is complete, there will be a green indicator there.

It’s easy to see in the photo below how much of the cell length is actually charge circuit.  Maybe 1/4 of the cell size?  Probably a decent trade off though, because the average charger will not be all that fit for a 10440 cell.  These cells need a slow charge rate!

And this built in circuit provides that slow rate; the max charge rate is around 0.35A.  That’s probably around 1C (though I don’t see capacity for the cell reported anywhere).  My test (which records from the USB source) shows around 210mAh went into the cell.  (And that’s 210mAh at 5V, so you could math it out to see the actual capacity – something like 250mAh).  The charge circuit looks great, too.

PWM

Surprisingly there appears to be PWM on all modes except Turbo.  I say “surprisingly”, because I can’t see a single bit of PWM at all.  And I’m super sensitive to PWM.  I call this a win, and if I were you I wouldn’t worry about this at all.

For reference, here’s a baseline shot, with all the room lights off and almost nothing hitting the sensor.

User Interface and Operation

There’s a single switch on the EDC C1.  It’s a tail e-switch.  There’s a nice flat rubber cover, and with little effort the light will tailstand on this switch.  The switch isn’t loud at all, but does make an audible “click” when …. clicked.

An e-switch in the tail of a light is unusual!

Here’s a UI table!  It’s a fairly feature rich UI. There are even two groups! The default is the “Illumination Group”, which is described in the table below.

State Action Result
Off Click On (Mode Memory excluding Turbo/Moon)
Off Hold Moonlight
Any Double click Turbo
On Click Mode Advance (LMHML)
Turbo Double Click Special Modes (And then special mode advance) (Strobe>SOS>Beacon>Turbo)
On Hold Off
Off Click 3x Lockout
Lockout Click 3x Unlock (to “Off”)
Any Click 7x Switch to Tactical Group

Below is the table for the Tactical Group.

LED and Beam

One of the very unusual things about this light is that it’s one of the first production lights with a Nichia E21a emitter.  This is a 3000K temperature, and >95 CRI.  (To be honest, this light had me right there – it’s great to try new emitters, and this one’s interesting in it’s own right – and for ~$35 in a brass light – yes please.)

The reflector is smooth, and coupled with the domeless nature of the E21a, provides a surprising amount of throw for such a tiny package.  It also means that as a keychain light, there’s probably more of a spot than is needed.  But for walking around the house at night and checking on kids or whatever, this light is fantastic!!

These beamshots are always with the following settings:  f8, ISO100, 0.3s shutter, and manual 5000K exposure.

Tint vs BLF-348 (Killzone 219b version)

This is the same shot as above, but exposed differently, for easier beam comparison.

I compare everything to the Killzone 219b BLF-348, because it’s inexpensive, has the best tint, and [probably] still available!

All my Folomov reviews!

* Standard measurement disclaimer:  I am an amateur flashlight reviewer.  I don’t have $10,000 or even $1,000 worth of testing equipment.  I test output and such in PVC tubes!!  Please consider claims within 10% of what I measure to be perfectly reasonable (accurate, even).
